To all whom it may concern:

Be it known that I, ENGLAND 'J. Barman, a cltizen of the United States,residing at Chicago, in the county of Cook and, State of Illinois, haveinvented new and useful Improvements in Paper-Supply Attachments forType-Writing Machines, of which the following is a full, clear, andexact de scription. I

My invention relates to improvements in paper supply attachments fortypewriters,

and of the mechanism of the paper supply attachment carrying the samewhich are actuated by the reciprocable carriage of the typewritingmachine; to simplify the mechanlsm for transmitting the rotatablemovement of the platen of the typewriting machine to the paper feedrolls of the stationary paper supply attachment, and to protect and keepthe paper, and particularly the pendent slack portion thereof free frominterference. These and other objects I accomplish by the meanshereinafter fully described, and as particularly pointed out in theclaims. r

In the drawings: 1

My improvements affect thetypewriting machine (hereinafter referredto'as the typewriter), the table upon which the same is mounted and thepaper supply attachment therefor including the framework upon which therolls of paper are j ournaled. The table may be. constructed in anysuitable manner, but I prefer to make it with a wooden top A, and with asupport therefor consisting of angle-iron legs a connected at the top bymetal rails a and near their feet with metal side-rails a Side-rails aare connected by a cross-bar a and the feet of metal uprights B, B,which are located adjacent the rear legs a rest upon and are. secured toand supported on thiscross-bar.

a and have their upper portions, just before they reach the upper rail,curve to the rear and then upward through the end portions of atransverse'slot C made in the table top just to the rear of thesupporting frame of the typewriter. A short distance above the table topthese uprights are suitably secured to'lugs or screw-plates b, 6,projecting rearwardly from the rear vertical members of the frame-workof the typewriter, and said uprights are bent laterally over the upperedges of said screw-plates and then vertically and rearwardly for theremainder ofthe upper portions. Below the table-top uprights B, B, areeach provided with a corresponding series of equi-distant pairs of arms0, c, that terminate a suitable dise tance in front of the rear legs aand are each connected to its mate by a stationary shaft 0. The ends ofshaft '0 extend through arms a and are screw-threaded and have nuts 0screwed thereon that retain the shafts in assembled position and yetpermit their withdrawal longitudinally from said arms, when desired.Rollers D are loosely journaled on shaft and rolls of paper E aremounted on said rollers.

About midway between the upper ends of uprights B and the lugs orscrew-plates Y b of the typewriter frame-work said uprights areconnected by a cross-bar (Z and are also provided near said upper endswith bearings for the eccentric ends f of a normally stationary shaft F.A suitable crank F is secured on the extended end of one of saideccentric ends, and between the boss of this crank and the upright askewed split washer f is interposed that provides sufficient resistanceto the rotation of shaft F to hold it in any position to which it may beturned. A suitable roller G is lossely mounted on shaft 'F between itseccentric journals, and the webs of paper from rolls E are fed upthrough slot 0 to and over roller G and then downward through atransversely elongated opening 9 in the top of the table which islocated, preferably, in the same transverse vertical plane as therearmost segment of said roller.

Below the table-top the paper hanging from roller G enters a basket orcage H, which latter, as showmin the drawings, consistsof a skeletonframe-work comprising vertical corner strips it the upper ends of whichare connected to a rectangular metallic edge-frame k and the lower endsof the corner strips on the same side being connected by a bottom strip72/. The spaces between the parts of this skeleton frame are closed bycoarse wire screening, and the basket is supported by attaching theforward corner strips 71, to the rear legs of the table. 4

' The webs of paper that hang down from roller F into the basket -Hreach to very near the bottom of the basket and then extend verticallyupward through a transversely elongated slot 9 in the table-top to aseries of horizontal guide-bars j. These ide-bars 7' have their endssuitably secured 1n the rear vertically extended ends of the side-framesJ of a bracket, that is supported by the carriage of the typewriter andoverhangs the roller in such manner that a line drawn through the axesthereofwill incline to the rear. This disposition of bars 7' separatesthe webs of paper passing over each roller from each other, and fromthese guidebars j said webs of paper pass horizontally forward to andover a vertically disposed series of guide-bars j whose ends aresuitably secured in the vertically extended forward ends of side-framesJ of the bracket. These side-frames J v are supported by and attached tothe upper ends K of a U-frame the connecting horizontal portion of whichrests upon and is secured to a horizontal platform I projectingrearwardly from the transversely reciprocable carriage L which issupported on the lower stationary supporting-frame M of the typewriter.As the bracket and its guidebars j and is move with the carriage theportions of the webs of pa per engaging said bars are moved from side toside, but in view of the extent of the slack portion of the paperhanging down into basket H the portion of the webs of paper thus movedfrom side to side will not effect the forward travel of said paperbetween bars j and k. In order to avoid any possible lateral movement ofthe strips as they pass over the bracket, however, I have providedguards m which consist of a straight barhaving openings through whichbars j and it pass. These guards are secured in any proper position towhich they may be adjusted by vmeans of set-screws m tappedlongitudinally through their upper ends and bite into the upperguide-bars.

After leaving guide-bars la the webs of paper pass downwardly andforwardly to and under the platen O of the typewriter, and after leavingthe latter extend up over a shield P. This shield consists of a flatplate whose lower horizontal edge is, preferably, straight andextendsfrom very near one end of the platen to the other, and this plateinclines upward and backward from its lower edge. The ends of shield Pare provided with rearwardly bent portions P that are secured to abridge 1; that has its ends secured to the end-frames of the carriage ofthe typewriter, and the upper edge of this shield is, preferably, midwayits ends extended upward higher than the remainder thereof to preventthe typewritten webs of paper from falling back upon the incomingunwritten portions of the same.

.The tearing-bar Q on which the webs of paper are torn off, after theyleave the platen, comprises a horizontal bar extending parallel to andin front of the platen in' a plane slightly below the edge of theshield, and is, preferably, rectangular in cross-section, and the endsof this tearingbar are attached to and are supported by the lower endsof corresponding arms 9 whose upper ends are pivotally connected in any'suitable manner to the rearwardly bent'ends P of the shield adjacenttheir upper edges. These arms g are Provided at oints near their upperends with lateral plns 9 that project toward the center of length of theshield, and are engaged by awls r, the upwardly hooked forward en s ofwhich latter are kept in engagement with said pins by means of a spring1" wound around a horizontal shaft R, which latter is supported in theend portions P of the shield; one end of said spring 1" being fastenedto shaft R and the other endbearing, as hown in Fig. 8 of the drawings,against bridge p..- The tearing-bar is normal y in position for the websof paper to betorn of on its upper edge 7 near the platen, but when thesaid webs are being threaded through the machine, said tearing-bar canbe raised upward and forward, after it has been released by depressg thepawl r, so a to disengage the latter from P 9" a It is necessary tomaintain the hangmg slack portion of the webs of paper suspended betweenroller G and guide bars 9'. This I accomplish by means of a m1lledroller S that engages roller G and is loosely mounted upon a transversehorizontal shaft S between a couple of standards S secured to andarising from bridge (1. The right-hand end of this bridge is extendedbeyond the side of the stationary supporting-frame M of the typewriter,and shaft S is correspondingly extended and journaled in bearmgs arismgfrom the ends of the same, and between the milled roller S and itsright-hand bearing said shaft S isprovided with longitudinal grooves t.A sprocket-wheel T is mounted on the grooved portion of shaft S the bossof which is elongated on either side of the same a suitable distance,and this boss has an annulus 2 at one end the bore of which is the sameas that of said boss and has a series of equi-distant pockets thereinfor the reception of steel balls .9 which engage longitudmal grooves 25in shaft S and cause the sprocket to impart its revoluble movement 0shaft S, but leaves the sprocket free to m ve longitudinally thereon.An.- nulus z is secured to the boss of sprocket T by a circular plate Yand screws tapped through the same. At one end the boss ofsaid procket Tis provided with two circumferentlal flanges, and channel ubetween theseflanges is engaged by the end of a rearwardly extendin arm '0 theopposite end of which is suitably secured to one of the upright ends 6of the U-shaped frame mounted on platform Z that moves back and forthwith the carriage; thus causing the sprocket to always malntain itsrelative position to said carriage. Sprocket T is driven through themedium of a' chain V by a sprocket-wheel U that is made integral withthe boss of an idle-gear w, and is journaled on the barrel of a screw Wtapped into the end-frame of the carriage, and this gear w is driven bya suitable gear X securely mounted on the adjacent extended end of thejournal of platen C. This journal may extend through gear X and have amilled wheel a: mounted thereon,if desired, and when the laten is turnedthrough the medium of whee m, gear X imparts it motion to gear w (thesegears bemg of the same diameter as the platen) and sprocket U impartsits motion to sprocket T, and through it rotates shaft S and milledroller S. The portion of the circumference,

sult.

- When it is desired to disengage rollers S and G and stop the movementof the webs of paper that cause the hanging slack,handle F is turned soas to move shaft F and roller G away from and out of contact with rollerS, and when this is done the split washer f Wlll retain roller G in anyposition away from roller S to which it may be moved.
